Wow! would you happen to have a species list? This place sounds very interesting - also wondering whether it is safely accessible by foot from Kegon Falls/the Eastern side of Lake Chuzenji?
Wow ..
Makes Berlin Aquarium's offering of amphibians look paltry in comparison !
I recall there was a song about an axolotl I rather enjoyed ..
